Keynote Speech III Heterogeneous Catalysis and Environmental Nanomaterials for Water Decontamination: Promises, Challenges and Research Needs Abstract: Heterogeneous catalysis for environmental remediation has been a fertile research field in the recent decades. For environmental applications of the heterogeneous catalysis, environmentally-benign, efficient and robust catalysts are desired for the removal of hazardous substances in waste streams. This presentation will cover an overview of applications of the heterogeneous catalysis in environmental remediation with specific focus on water treatment. Several examples of nanomaterials and nanocomposites which have been developed for water remediation will be presented. Among these include photocatalyst/adsorbent composite for synergistic adsorption-photocatalysis, photocatalytic ceramic membrane for simultaneous separation and degradation of organic pollutants, bismuth ferrite for switchable multiplex catalysis under light and dark conditions, metal oxide catalysts for catalytic activation of peroxymonosulfate and generation of sulfate radical, and carbocatalysts. Despite immense researches and significant progress in developing advanced nanomaterials, there remain several challenges for field-scale adoption of heterogeneous catalytic processes in water decontamination. The final part of this presentation will provide a snapshot of these challenges and the future research needs to propel the research toward achieving practical adoption of heterogeneous environmental catalysis in water treatment.
